RESUMEN
Objective: The objective of this study was to analyze the risk of malignancy and the histopathology of telomerase reverse transcriptase promoter (TERT) mutated cytologically indeterminate thyroid nodules (ITN). Methods: A PUBMED search of molecularly tested ITN was conducted and data on TERT mutated ITN with histopathology correlation were extracted. Results: Twenty-six manuscripts (published between 2014 and 2022) reported on 77 TERT mutated ITN. Sixty-five nodules were malignant (84 %), with 16 (25 %) described with high-risk histopathology, 5 (8 %) described as low-risk, and most without any description. Isolated TERT mutations were malignant in 26/30 ITNs (87 %) with 9 (35 %) described as high risk and none described as low risk. TERT + RAS mutated ITNs were malignant in 29/34 ITNs (85 %) with 3 (10 %) described as high risk and 4 (14 %) described as low risk. Finally, all 5 TERT + BRAFV600E mutated nodules were malignant and 3/5 (60 %) were described as high risk. Conclusion: TERT mutated ITNs have a high risk of malignancy (84 %), and the current data does not show a difference in malignancy rate between isolated TERT mutations and TERT + RAS co-mutated ITNs. When described, TERT + RAS co-mutated ITNs did not have a higher rate of high-risk histopathology as compared to isolated TERT mutated lesions. Most TERT mutated ITNs did not have a description of histopathology risk and the oncologic outcomes, including rate of recurrence, metastases, and disease specific survival, are unknown. Further data is needed to determine if TERT mutated ITNs should be subjected to aggressive initial treatment.
RESUMEN
One of the complex challenges faced presently by tissue engineering (TE) is the development of vascularized constructs that accurately mimic the extracellular matrix (ECM) of native tissue in which they are inserted to promote vessel growth and, consequently, wound healing and tissue regeneration. TE technique is characterized by several stages, starting from the choice of cell culture and the more appropriate scaffold material that can adequately support and supply them with the necessary biological cues for microvessel development. The next step is to analyze the attained microvasculature, which is reliant on the available labeling and microscopy techniques to visualize the network, as well as metrics employed to characterize it. These are usually attained with the use of software, which has been cited in several works, although no clear standard procedure has been observed to promote the reproduction of the cell response analysis. The present review analyzes not only the various steps previously described in terms of the current standards for evaluation, but also surveys some of the available metrics and software used to quantify networks, along with the detection of analysis limitations and future improvements that could lead to considerable progress for angiogenesis evaluation and application in TE research.

OBJECTIVE: Case reports of postvaccine early-onset Graves' hyperthyroidism (PVGD) after the administration of COVID-19 vaccination have emerged. Our aim was to investigate whether the incidence of Graves' hyperthyroidism (GD) has increased after the introduction of COVID-19 vaccination. METHODS: We compared the incidence of new-onset GD at a single academic center during 2 periods: December 2017 to October 2019 and December 2020 to October 2022, ie, before and after the implementation of COVID-19 vaccinations. We defined PVGD as laboratory-confirmed hyperthyroidism and GD within 4 weeks after the vaccination or clear onset of symptoms of thyrotoxicosis within 4 weeks of vaccination with evidence of hyperthyroidism and GD within 3 months. RESULTS: During the prevaccination period, 803 patients carried diagnoses of GD, and of these, 131 were new. During the postvaccination period, 901 patients carried diagnoses of GD, and of these, 138 were new. There was no statistically significant difference in the incidence of GD (P = .52), age at onset, gender, or race between the 2 groups. Twenty-four of 138 newly diagnosed patients in the post-COVID-19 group met the criteria for PVGD. The median free T4 was higher, but this was not statistically significant (3.9 vs 2.5 ng/dL, P = .05). There were no differences in age, gender, race, antibody titers, or type of vaccination between PVGD and controls. CONCLUSION: There was no increase in new-onset GD after COVID-19 vaccination. Median free T4 was higher in patients with PVGD, but this was not statistically significant.

OBJECTIVE: To explore parent perspectives on barriers, facilitators, and priorities related to coordinating care for children and youth with special health care needs (CYSHCN). METHODS: Thirty-nine parents of Medicaid-eligible CYSHCN participated in focus groups and completed a brief survey about their child's health insurance coverage, access to specialized services, and need for support with service coordination. Survey data were analyzed using descriptive statistics. Focus group data were analyzed by multiple independent coders using an approach that combines inductive reasoning with predetermined coding strategies. RESULTS: Sixty-seven percent of parents reported that they needed care coordination support. Qualitative data were organized into three main themes: the work of caregiving; the impact of caregiving on multiple aspects of parents' lives; and caregivers' needs related to emotional acceptance, service referrals and navigation, and developmental transitions. CONCLUSIONS: Findings support importance of services such as medical homes, care coordinators, peer navigators, respite care, and transition planning.

A total of 15 individuals with cervical dystonia and good outcome after pallidal deep brain stimulation underwent resting-state functional magnetic resonance imaging under three conditions: stimulation using a priori clinically determined optimal settings (ON-Op), non-optimal settings (ON-NOp), and stimulation off (OFF). ON-Op > OFF and ON-Op > ON-NOp were both associated with significant deactivation within sensorimotor cortex (changes not seen with ON-NOp > OFF). Brain responses to stimulation were related to individual long-term clinical improvement (R = 0.73, R2 = 0.53, p = 0.001). The relationship was consistent when this model included four additional patients with generalized or truncal dystonia. These findings highlight the potential for immediate imaging-based biomarkers of clinical efficacy. ANN NEUROL 2022;92:418-424.

Deep brain stimulation targeting the subcallosal cingulate area, a hub with multiple axonal projections, has shown therapeutic potential for treatment-resistant mood disorders. While subcallosal cingulate deep brain stimulation drives long-term metabolic changes in corticolimbic circuits, the brain areas that are directly modulated by electrical stimulation of this region are not known. We used 3.0â T functional MRI to map the topography of acute brain changes produced by stimulation in an initial cohort of 12 patients with fully implanted deep brain stimulation devices targeting the subcallosal cingulate area. Four additional subcallosal cingulate deep brain stimulation patients were also scanned and employed as a validation cohort. Participants underwent resting state scans (n = 78 acquisitions overall) during (i) inactive deep brain stimulation; (ii) clinically optimal active deep brain stimulation; and (iii) suboptimal active deep brain stimulation. All scans were acquired within a single MRI session, each separated by a 5-min washout period. Analysis of the amplitude of low-frequency fluctuations in each sequence indicated that clinically optimal deep brain stimulation reduced spontaneous brain activity in several areas, including the bilateral dorsal anterior cingulate cortex, the bilateral posterior cingulate cortex, the bilateral precuneus and the left inferior parietal lobule (PBonferroni < 0.0001). Stimulation-induced dorsal anterior cingulate cortex signal reduction correlated with immediate within-session mood fluctuations, was greater at optimal versus suboptimal settings and was related to local cingulum bundle engagement. Moreover, linear modelling showed that immediate changes in dorsal anterior cingulate cortex, posterior cingulate cortex and precuneus activity could predict individual long-term antidepressant improvement. A model derived from the primary cohort that incorporated amplitude of low-frequency fluctuations changes in these three areas (along with preoperative symptom severity) explained 55% of the variance in clinical improvement in that cohort. The same model also explained 93% of the variance in the out-of-sample validation cohort. Additionally, all three brain areas exhibited significant changes in functional connectivity between active and inactive deep brain stimulation states (PBonferroni < 0.01). These results provide insight into the network-level mechanisms of subcallosal cingulate deep brain stimulation and point towards potential acute biomarkers of clinical response that could help to optimize and personalize this therapy.

BACKGROUND/OBJECTIVES: Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare skin tumor. The head and neck (H&N) is the most common anatomical location. Due to limited published cases, its clinical course and management are not well understood. METHODS: The National Cancer Database (NCDB) was queried for all cases of H&N PCACC diagnosed from 2004 to 2016. Kaplan-Meier (KM) and Cox proportional hazards models were used to determine clinicopathological and treatment factors associated with survival outcomes. RESULTS: A total of 201 cases were analyzed. The average age of diagnosis was 57.7 years (± SD 15.8). There was a female predilection (57.7%; P < .05) with the most common primary site being the ear (58.2%). The average tumor size was 15.9 mm in diameter. The most common treatment was surgery alone (51.7%) with wide local excision being the common surgery performed (36.3%). 5-year and 10-year OS were 87.0% and 76.0%, respectively. A total of 65.8% of cases were localized (Stage I and II). KM analysis indicated that gender, age, insurance status, Charlson-Deyo Comobordity Score, and stage were significant predictors of OS (P < .05). Cox proportional hazards analysis revealed that patients with both private (HR 0.11, 95%CI [0.019-0.670]; P = .02) and government (HR 0.12, 95%CI [0.019-0.972]; P = .03) health insurance had a significantly decreased hazard of death than patients who were uninsured. Increasing age was associated with an increased hazard of death (HR 1.06, 95%CI [1.016-1.110]; P = .01). CONCLUSION: This study represents the largest cohort of H&N PCACC studied to date and provides important clinicopathologic information for this rare tumor. Additionally, our results emphasize the importance of health insurance as an independent predictor of survival in PCACC.

BACKGROUND/OBJECTIVES: Primary cutaneous mucinous carcinoma (PCMC) of the head and neck is a rare pathologic entity that is an adenocarcinoma of the eccrine sweat glands. Though it has low metastatic potential, it does have a significant recurrence rate. Due to its rarity, its clinical features are not well-known. METHODS: The authors searched the National Cancer Database (NCDB) for all cases of PCMC with primary sites of the skin of the head and neck confirmed histologically diagnosed from 2004 to 2016. Those with missing survival information were excluded. Kaplan-Meier (KM) and Cox proportional-hazards models were used to analyze the epidemiology and survival outcomes of PCMC. RESULTS: The authors analyzed 289 cases. Females were more commonly affected (58.8%; Pâ<â0.05) with the most common primary sites being the eyelid (41.9%) and scalp/neck (25.3%). The average age of diagnosis was 63.8 years (± SD 12.5). Almost all patients received surgery as standalone treatment (92.7%) with wide local excision being the common surgery performed (36.3%). Mohs surgery represented 15.2% of surgically treated cases. Mean overall survival (OS) was 11.4 years with 5-year and 10-year OS being 85.0% and 78.0%, respectively. Most cases were localized at diagnosis with only 2% metastatic at presentation. KM analysis indicated that surgical procedure type, age, tumor diameter, Charlson-Deyo Comorbidity Score, facility type, and stage were significant predictors of OS (Pâ<â0.05). Cox proportional-hazards analysis did not reveal independent association of the aforementioned factors with OS. CONCLUSION: Primary cutaneous mucinous carcinoma has an excellent prognosis with 98% of cases being diagnosed in Stage I and Stage II. As most cases present in the eyelid, special attention should be given to surgical treatment to ensure optimal aesthetic outcomes in this sensitive region. This study represents the largest cohort of head and neck PCMC studied to date.

Studies on microcystic adnexal carcinoma (MAC) survival rates have been limited. This effort examines the association of patient demographics, treatment modalities, and tumor stage with overall survival (OS) in patients with MAC of the head and neck. All cases of MAC with primary sites of the skin of the head and neck, confirmed histologically, and diagnosed from 2004 to 2016 in the National Cancer Database, were analyzed. We utilized Kaplan-Meier and Cox proportional-hazard models to analyze the characteristics and survival outcomes of the 415 cases that met the criteria. The mean age of diagnosis was 63.8 years (SD ±15.8). Mean OS was 10.8 years with 5- and 10-year OS being 81.0% and 68.0%, respectively. Women were more frequently affected (59.0%; P < .001). Stand-alone primary site surgery was the most common treatment (81.4%): 15.9% of patients were treated with postexcision radiation therapy (RT). 18.3% were treated with RT with or without surgery and/or chemotherapy. RT was independently associated with a decreased hazard of death (HR = 0.23; P = .044). MAC of the head and neck disproportionately affects whites, is more common in women, and has the potential to metastasize. Surgical excision is the commonest treatment; our study shows benefit from judicious RT.

OBJECTIVE: To perform an evidence-based systematic review evaluating perioperative analgesia, including opioid alternatives, used for patients undergoing thyroidectomy and parathyroidectomy. METHODS: A comprehensive literature search from 1997 to January 2018 of Pubmed, Cochrane, and EmBase libraries was performed for studies reporting analgesic administration following thyroid or parathyroid surgery. This systematic review was based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Studies were evaluated for level of evidence and given a Jadad score to assess for risk of bias. Outcomes gathered included postoperative pain scores, time to rescue analgesia, rescue analgesic consumption, and adverse events. RESULTS: Thirty-eight randomized controlled trials met inclusion criteria. The GRADE criteria determined the overall evidence to be moderate-high. Studies utilizing NSAIDs reported reduced requirements for rescue analgesics. Acetaminophen studies presented with conflicting data on effectiveness. Gabapentinoid studies demonstrated lower pain scores and an increased time to rescue analgesic. Local anesthetics were effective at decreasing Visual Analogue Scale (VAS) and Numeric Rating Scale (NRS) pain scores while also reducing rescue analgesic consumption. Ketamine was shown to increased postoperative nausea and vomiting. NSAIDs and local anesthetic studies had an aggregate grade of evidence A, while all others had grade B evidence. CONCLUSION: There is significant evidence supporting the use of NSAIDs and local anesthetics in the perioperative period for pain management for thyroid and parathyroid surgeries. Acetaminophen, gabapentinoid and ketamine have some supporting evidence and may serve as adequate alternatives. Further multi-institutional RCTs are warranted to delineate optimal analgesic regimens. LEVEL OF EVIDENCE: NA.

IMPACT STATEMENT: Recently, the use of photodynamic therapy grows as an alternative treatment for cancer, since it has a noninvasive characteristic and affinity to the tumor tissue. Accordingly, understanding the therapy's foci of action is important for the technique improvement. This work aims to understand the genotoxic effect triggered by the therapy action, thus evidencing the permanent changes caused to the genetic material of the tumor cell after the treatment. Therefore, to increase the knowledge in this study field, the methodology of the comet assay and count of micronucleus formed after the therapy was adopted in order to understand if the damage caused to the DNA of tumor cell makes its replication process unfeasible in future generations. The study allows a better therapeutic approach to the cancer treatment, making the process of association between therapies a more effective option during the disease treatment.

AIM: Despite Australia's high vaccination rates, an estimated 3.3% of children are under-vaccinated due to vaccine refusal and the proportion of parents with concerns is unclear. Amongst Australian parents, we aimed to determine the prevalence of vaccine concerns, resources and health-care providers (HCPs) accessed and satisfaction with these resources in two different settings. We also aimed to identify relationships between the level of vaccine concern, socio-economic status and vaccine uptake. METHODS: Parents of children under 5 years attending general paediatric clinics in a tertiary paediatric hospital (n = 301/398, 76%) and children under 19 months attending community maternal child health centres (n = 311/391, 81%) completed the survey. Vaccination status was obtained from the Australian Childhood Immunisation Register. RESULTS: Despite high support for vaccination (98%, confidence interval (CI) 97-99), 43% of parents reported vaccine concerns (CI 40-47) including the number of vaccines given in the first 2 years (25%, CI 22 to 29), vaccine ingredients (22%, CI 19-25), allergies (18%, CI 15-21), weakening of the immune system (17%, CI 14-20) and autism (11%, CI 8-13). HCPs were the most commonly accessed and trusted information source. In all, 23% of parents reported insufficient knowledge to make good vaccination decisions (CI 20-26). There was little evidence of an association between parental vaccine acceptance or socio-economic status and vaccination status. CONCLUSIONS: Despite high support for vaccines, nearly half of Australian parents have some concerns and a quarter lack vaccine decision-making confidence regarding childhood vaccines. Parents frequently access and report high trust in HCPs, who are best placed to address parental vaccine concerns through provision of clear information, using effective communication strategies. Further research in more highly hesitant populations is required to determine the relationship between the level and nature of vaccination concerns and vaccine uptake.

Immunoglobulins are heterodimeric proteins composed of 2 heavy chains and 2 light chains. Human immunoglobulin G (IgG) is a plasma derivative and contains more than 95% of IgG. The composition of IgG subclasses is similar to that of normal human plasma. Immunoglobulin therapy was first introduced more than 50 years ago, and its use has been described in numerous diseases. In Colombia, the importance of this immunomodulatory resource prompted the need for clinical practice guidelines to be available for its use. For this reason, a multidisciplinary group of experts was brought together and distributed in working groups, by specialties, in order to develop an initial manuscript. Systematic literature searches were undertaken; identified evidences were evaluated and classified to support a preliminary draft that was discussed, analyzed and amended. Recommendations were issued on the use of intravenous immunoglobulin in pathologies that include primary and secondary immunodeficiencies, autoimmune diseas es, neurological disorders, infections, transplants and miscellaneous conditions; grades were assigned to each one of them according to the GRADE system. The final result translated into recommendations that are put forth with the purpose to inform, guide and support on optimal use of this immunomodulatory resource.

La composición de las subclases de IgG es similar a la del plasma humano normal. El tratamiento con inmunoglobulina comenzó hace más de 50 años y su uso se ha descrito en numerosas enfermedades. En Colombia, la importancia de este recurso inmunomodulador condujo a la necesidad de contar con una guía de práctica clínica para su uso, para lo cual se reunió un grupo multidisciplinario de expertos, quienes se distribuyeron en mesas de trabajo, por especialidad, para redactar un texto base. Se llevaron a cabo búsquedas bibliográficas sistemáticas; las evidencias identificadas se valoraron y clasificaron para sustentar un texto preliminar que fue discutido, analizado y corregido. Se emitieron recomendaciones de uso de la inmunoglobulina intravenosa en patologías que abarcan inmunodeficiencias primarias y secundarias, enfermedades autoinmunes, alteraciones neurológicas, infecciones, trasplantes y enfermedades misceláneas; se asignaron calificaciones según el sistema GRADE para cada una. El resultado final se tradujo en las recomendaciones que se presentan con la finalidad de informar, orientar y apoyar en el uso óptimo de dicho recurso inmunomodulador.

AIM: Health-care providers are crucial in maintaining parental confidence in vaccination. Health-care providers are the most commonly accessed resource by parents for vaccine-related information and are highly trusted. We investigated paediatricians' (i) frequency of vaccine discussions; (ii) specific vaccine-related topics discussed; (iii) perceived role in childhood vaccination; (iv) challenges faced when having discussions; (v) confidence in vaccine-related knowledge and communication skills; and (vi) interest in online education and training. METHODS: We invited members of the Australian Paediatric Research Network to complete an online Research Electronic Data Capture survey in 2015-2016. RESULTS: Of 383 active Australian Paediatric Research Network members, 165 (43%) completed the online survey. A total of 61% reported 'frequently' or 'almost always' having vaccine-related discussions, with 15% 'rarely' having them. 'Lack of time' was the most commonly reported barrier to having vaccine discussions (54%). Vaccine necessity was most commonly discussed (33%), followed by vaccine safety (24%), general vaccine concerns (23%) and catch-up schedules (23%). While only 25% of paediatricians lacked confidence in their vaccine-related knowledge and 11% in their communication skills, most expressed interest in online training to address vaccine knowledge (62%) and communication skills (53%). CONCLUSION: Paediatricians play a key role in maintaining public confidence in vaccination. However, opportunities to address concerns are not being maximised by Australian paediatricians. There is a need and desire for training and resources to increase vaccine knowledge and communication skills for paediatricians, to optimise the frequency and effectiveness of vaccine discussions with parents and to ensure ongoing high immunisation coverage rates in Australia.

Abstract Hemophagocytic syndrome is an entity caused by hypercytokinemia and impaired immune system, may be hereditary or acquired and generates high mortality despite treatment. Among the etiologies, infections occupy an important place, one of them disseminated histoplasmosis, an opportunistic infection of difficult diagnosis which affects immunosuppressed patients. We present the case of an adult patient, with renal transplant who developed hemophagocytic syndrome secondary to disseminated histoplasmosis and responded adequately to the antifungal treatment.
Resumen El síndrome hemofagocítico es una entidad causada por hipercitoquinemia y alteraciones del sistema inmune, puede ser hereditario o adquirido y genera alta mortalidad pese al tratamiento. Dentro de las etiologías, las infecciones ocupan un lugar importante, una de ellas la histoplasmosis diseminada, infección oportunista de difícil diagnóstico que afecta a pacientes inmunosuprimidos. Presentamos el caso de una paciente, adulta mayor, trasplantada de riñón, quien presenta síndrome hemofagocítico secundario a histoplasmosis diseminada y, quien presenta respuesta adecuada con el tratamiento instaurado.

While nursing leaders play an important role in supporting new nurse graduates during their transition period, few studies have explored the perceptions of nursing leaders involved in transition support programs. A study was undertaken to explore the nursing leadership teams' perceptions of their role and the benefits and challenges of the Genesis Transition Support Program for New Nurse Graduates at McGill University Healthcare Centre, Quebec, Canada.A qualitative descriptive study design was used. Semistructured individual interviews were conducted with 12 nursing leaders from September to October 2013. Data analysis revealed 3 main themes regarding nursing leaders' role within the program: planning for the seminar, providing active learning opportunities and supporting new nurse graduates by listening, understanding, helping, and building stronger relationships. The program is largely associated with an enhanced experience of new nurse graduates transitioning into their professional role and has a positive impact on new nurse graduates, nursing leaders, and their individual nursing units.

The composition and antifungal activity of the essential oil (EO) of Angelica major and its main components α-pinene and cis-ß-ocimene against clinically relevant yeasts and moulds were evaluated. EO from the plant's aerial parts was obtained by hydrodistillation and analysed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The oil showed high contents of α-pinene (21.8 %) and cis-ß-ocimene (30.4 %). Minimum inhibitory concentrations (MICs) were measured according to the broth macrodilution protocols by the Clinical and Laboratory Standards Institute (CLSI). The EO, α-pinene and cis-ß-ocimene displayed low MICs and minimum fungicidal concentrations (MFCs) against dermatophytes and Cryptococcus neoformans, with α-pinene being the most active. Regarding Candida species, the EO susceptibility profiles seem to be diverse and not correlated with fluconazole susceptibility patterns. Moreover, an inhibition of yeast-mycelium transition was demonstrated at sub-inhibitory concentrations of the EO, α-pinene and cis-ß-ocimene in C. albicans. In addition, their haemolytic activity was low. The activity displayed by A. major EO and its main components associated with low cytotoxic activity confirms their potential as an antifungal agent against fungal species frequently implicated in human mycoses, particularly cryptococcosis and dermatophytosis. The association with commercial antifungal compounds could bring benefits, by the effect on germ tube formation, and be used in mucocutaneous candidiasis treatment.
